VISBLESTRIP SCREED AND GROUND.

Application led February 26, 1927. Serial No. 171,257.

This invention relates to a visible strip screed and ground for use inapplying wood or metal trim in lireproof construction work.

An important object of theinvention is to provide a device of thischaracter' which is readily embedded in the finishing plaster work andwhich, in applied position, will be visible and readily accessible forthe attachment of trim thereto. n

A further object of the invention is to produce a readily constructedscreed of suoli formation that it provides a socket-for the reception ofa Wood block affording any attachment means and so houses the block thatit cannot fall out should it be split in use.

These and other objects we attain by the construction shown in theaccompanying drawings, wherein for the purposevof illustration is shownapreferred embodiment of our invention and wherein 1 Figure 1 is a planView of a screed con-v structed in accordance with our invention; Figure2 is a vertical sectional View show ing the same as applied `in thewall;`

Figure Sis a sectional view showing the blank from which the trough andits fianges are formed, the dotted lines indicating the points at whichthe blankis to be bent.

Referring now more particularly to the drawings, the numeral 10generally designates a trough formed from sheet metal and having at itssides outstanding flanges 11,

tacting the bottom Wall 12 of the trough and the upperends of the sidewalls 13. These flanges are preferably made sinuous, being at presentillustrated as having a single bend 14 formed therein intermediate theirattached and unattached edges. In. the flange are formed openings 15 and16 through which the wall plaster may pass to firmly lock the .screed inposition in the wall.

lVithin `the trough is arranged a wood block 17, this block having itsupper surfac(J substantially flush with the upper edges of the sideWalls and being retained in position in the trough by tabs 18 formedintegrally With the body of the trough. In the pres-p ent construction,the tabs 18 are formed by cutting the material of the flanges 11 adjatothe side walls 13 of the trough in a semicircle, the cord of which isthe attached edge of the fiange. The flap thus provided is then bentinwardly upon the upper surface of the wood block 17 to retain the samein position. A screed of this character is applied to the wall with thebottom of the trough outwardly disposed. The wood block being firmlyheld within the trough and reinforced by the plastering thereabout willnotfall out should it split `or break when the trim is lsecured thereto.Under manycircumstances, the tabs 18 are unnecessary, as the trough canbe made to grip the block with sulicient force to prevent loss theliicofbefore the screed is inserted in the wa Since the constructionhereinbefore set forth is capable of a certain range of change andmodification without materially de parting from the spirit of theinvention, we do not limit ourselves to such specific strueture exceptas hereinafter claimed.

lV e claim im v 1. A screed of the character described comprising atrough having flanges extending outwardly from the upper ends of theside walls thereof, said flanges lying wholly between parallel planescontacting the bottom of the trough and the upper ends of the side wallsthereof, said flanges being per forated, and a 4 wood blockl within saidwhich lie wholly within parallel planes contrough.

2.` A screed of the character described comprising a trough havingfianges extending outwardly from the upper ends of the side wallsthereof, said flanges lying wholly between parallel planes contactingthe bottom of the trough and the upper ends of the side walls thereof,said flanges `being perforated, and a wood block within said trough, thetrough having tabs engaging the wood block to maintain the same inposition therein, saidtabs being struck out from the material of theflange to thereby provide certain of said openings.

In testimony whereof we hereunto affix our signatures.
